I used to tell people choose telco with best coverage for you, now I'll say choose a telco that doesn't practice discrimination and double standards.

In other words, not maxis.

Things sold in East Malaysia sometimes cost more due to transportation and logistics. That said, I was in KK last week and had the privilege of visiting one of the newer malls and noticed that the price of most goods are already the same as in Peninsular Malaysia. It's not about protecting the minority or the majority, is about having two different prices for the same product when there is absolutely no reason to.

Actually, there is an underlying reason to it. Have to look at EM and WM as two different market segments and hence, a different marketing strategy is required to makan a larger market share. Its quite the same everywhere to be honest. Banks offer better FD rates to new customers versus old customers. Happy hour at your local pub.
Bro, Sabah and Sarawak are on an island. Fresh produce has to be air-flown in. Who will bear the cost of shipping the goods from WM to EM? If business absorb, then might as well not do business anymore right? The margin has to be decent enough otherwise it won't make sense to sell in EM right? Even if you start a farm/factory in EM, they will still need to fly it around. EM is so big! Hope this clarifies!
